City Airport may Let You Enter with Your Aadhaar

More than 1 billion people in India have been issued Aadhaar cards, for which facial, iris and fingerprint data are recorded into a national digital registry. The biometric data and digital identification numbers have been put to a number of uses, including for identity verification in issuing passports and direct transfer of cash subsidies under various welfare schemes. But for Bengaluru airport's initiative to have any security impact, several legal and procedural challenges have to be overcome, said Dubey. For one, Aadhaar cards are not mandatory and hundreds of thousands of passengers--both Indian citizens and foreigners--are unlikely to be registered with it.
